# Composition Over Inheritance / Simplicity for Trivial Reuse

> "composition-over-inheritance" (structural-core layer) is traded against "Simplicity for Trivial Reuse" (structural-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Simplicity for Trivial Reuse" and choosing an explicit operating point.
